Abstract
The invention concerns a method for continuously casting an austenitic stainless steel strip with a thickness not more than 10 mm, directly from liquid metal, between two cooled horizontal rolls, characterised in that: said steel composition in weight proportions comprises: %C<=0.08%; %Si<=1; %P<=0.04; %Mn<=2; %Cr between 17 and 20; %Ni between 8 and 10.5; %S between 0.007 and 0.040; the rest being iron and the impurities resulting from preparation; the ratio Creq/Nieq ranges between 1.55 and 1.90 with: Creq(%)=%Cr+1.37 %Mo+1.5 %Si+2%Nb+3 %Ti; Nieq(%)=%Ni+0.31 %Mn+22 %C+14.2 %N+Cu; the surface of the rolls comprises contiguous dimples with more or less circular or elliptical cross-section, of diameter between 100 and 1500 mum and depth between 20 and 150 mum; the inerting gas surrounding the meniscus is a gas soluble in steel or a mixture of such gases, or consists of at least 50% by volume of such a gas or mixture of gases.
